Prolonged Modulation of the Micturition Reflex by Electrical StimulationJiang, Chong-He January 1999 (has links)
Intravesical electrical stimulation (IVES) has been used in treatment of patients with urinary bladder dysfunctions for more than four decades. While some investigators have reported excellent results others have observed less convincing effects or outright failures. The discrepancies may reflect differences in patient selection or stimulation procedure. A better theoretical understanding of the IVES working mechanism might help to improve the success rate of the treatment. The aims of the present study were to provide such information. Experiments were performed on adult female cats and rats under /alpha/-chloralose anesthesia. IVES was delivered by a catheter electrode in the bladder. At proper intensity and frequency, IVES evoked reflex detrusor contractions that were abolished by bilateral rhizotomy of sacral dorsal roots. Stimulation parameters and response characteristics revealed that bladder mechanoreceptor A/delta/ afferents were activated by the IVES, the same afferents that drive the normal micturition reflex. Five minutes of continues IVES at 20 Hz induced a prolonged, significant decrease in the micturition threshold volume of anesthetized rats. Similarly, selective bladder A/delta/ afferent stimulation induced a long-lasting enhancement of micturition reflex discharges in cats. A comparable prolonged inhibitory effect on the micturition reflex was demonstrated after ano-genital afferent stimulation. Both modulatory effects occurred without changes in response sensitivity of stimulated afferents. The IVES induced modulation was prevented by transient exposure of the bladder to a local anesthetic and by systemic administration of a glutamate NMDA receptor antagonist. In conclusion, IVES induces a prolonged modulation of the micturition reflex by an LTP like enhancement of excitatory synaptic transmission in the central micturition reflex pathway. The findings provide an experimental explanation for the neuronal mechanisms underlying the curative effect of IVES in patients with bladder evacuation problems. / On the day of the public defence the status of article V was: Accepted.

Towards a Consummated Life: Kenneth Burke's Concept of Consummation as Critical Conversation and CatharsisBacalski, Cherise Marie 14 March 2013 (has links) (PDF)
Consummation was the one term about which Kenneth Burke wasn't particularly long-winded - odd considering his claim that it was the apex of his theory of form. Perhaps Burke never explained exactly what consummation was because he himself was never clear on the subject, as he told John Woodcock in an interview toward the end of his career. Burke began conceptualizing his theory of form early on - in his 20s - and published it in his first critical book, Counter-Statement, in 1931. At that time, Burke's theory of form had already taken one evolutionary step - from self-expression, with the focus on the artist, to communication, with the focus on the psychology of the reader. Communication was to Burke an "arousing and fulfilling of desires." However, by the 60s, Burke introduced us to a new term which he only used a handful of times in his entire corpus: consummation. This paper attempts to define consummation by exploring Burke's theory of form and looking to his correspondences with friends and scholars. It offers two answers: first, consummation is the act of a reader responding to a writer in critical conversation; second, consummation is the ultimate cathartic achievement. Both play an important civic role. Using current science regarding the gut in connection with emotional purgation, this paper treats seriously Burke's essay "The Thinking of the Body (Comments on the Imagery of Catharsis in Literature)" and his ideas regarding the "Demonic Trinity": micturition, defecation, and parturition, explaining Burkean catharsis as it differs from, deepens, and extends Aristotelian catharsis. What can we learn from what Burke meant by consummation? That the symbolic world is much more significant to our survival than we may realize. As the world of scientific motion advanced rapidly during Burke's lifetime, he began to lose hope that symbolic action could keep up with it. We can see how important poetry and the symbolic motive was for him; he seemed to think it was a matter of life and death. This paper explores what it meant for Burke to seek a consummated life, and the implications that held for him and for us. In the end, the paper posits the importance of catharsis to society in terms of war and peace.
